-> JavaScript implementation of the TCP module for libp2p. It exposes the [interface-transport](https://github.com/libp2p/interface-connection) for dial/listen. `libp2p-tcp` is a very thin shim that adds support for dialing to a `multiaddr`. This small shim will enable libp2p to use other different transports.
